MD 0054 CONCERNING SEVERE POTENTIAL…WATCH POSSIBLE FOR SOUTHERN MISSISSIPPI INTO ALABAMA

Mesoscale Discussion 0054
NWS Storm Prediction Center Norman OK
1011 AM CST Fri Jan 12 2024

Areas affected…southern Mississippi into Alabama

Concerning…Severe potential…Watch possible

Valid 121611Z – 122015Z

Probability of Watch Issuance…40 percent

SUMMARY…The area from southern and eastern Mississippi into
western and southern Alabama is being monitored for watch potential.

DISCUSSION…A low continues to deepen near the MS/AL border with
associated thunderstorm line segments. This area of storms near the
low has been producing 35-45 kt winds consistently. The air mass to
the east becomes progressively more stable with cooler temperatures
and lower dewpoints. Therefore, a ramp up in storm intensity is not
anticipated over much of northern AL.

Farther south, a warm front intersects the main cold front over
east-central MS, with better moisture spreading northward into
southwest AL and southern MS. Showers are developing in the warm
advection zone, but instability is generally below 1000 J/kg.

It is uncertain how much severe activity will occur over the next
few hours as the upper wave lifts north of the area, veering
low-level winds over the small warm sector and with limited lift.
Warm sector trends will continue to be monitored as destabilization
occurs into southern AL where lift along the warm front could
support a few severe storms.
